“…The most intense signals at δ = 0.86 and 3.52 ppm were assigned to phosphoric and phosphonic acid, respectively. The identity of the latter compound is confirmed by the presence of the H–P doublet ( 1 J PH = 653.0 Hz) in the 31 P NMR spectrum of the sample . A low-intensity nonbinomial 1:1:1 triplet of signals is observed at δ = 3.25 ( 1 J PD = 102.0 Hz) assigned to the deuterated form of phosphonic acid, ascribed to the H–D exchange between the deuterated solvent and protic phosphonic acid.…”

Deterioration of the surface of black phosphorus (BP) caused by ambient atmosphere is an undesired process, limiting broader use of BP in many areas. The mechanism of BP degradation was explained theoretically, and the oxidized materials were thoroughly characterized experimentally. However, the surface analysis techniques introduce only a limited insight into the real state of the material. Here, we report a thorough analysis of the composition of mixtures obtained after a prolonged exposure of suspensions of BP to atmospheric oxygen with the aim to further disclosure the processes involved in the decomposition process. The results are compared with the predicted structures of the oxidized material and confirm the results of the theoretical calculations. The comparison of reactivity of BP with reactivity of white phosphorus under similar conditions concludes a similar distribution of the products in both cases.

“…The hydrophosphorylation of Schiff bases with dialkyl phosphite, which can be considered as a Pudovik reaction applied to azomethines, or a Kabachnik-Fields reaction, can be performed in two separate steps with isolation of the intermediate imine, or in one pot, 24 all components being added at once, and in both cases the mechanism of this reaction remains unclear. 25,26 This hydrophosphorylation step was run in the presence of an excess of dimethyl phosphite used as solvent, as previously described for other PPH dendrimers in homogeneous conditions. 27 All materials were fully characterized by FTIR and 13 C, 31 P and 29 Si MAS NMR spectroscopies, which gave complementary information.…”

Comprehensive Organic Name Reactions and Reagents

This reaction is a base‐promoted nucleophilic addition of organophosphorus anion to alkenes or alkynes and is generally known as the Pudovik reaction. It has been reported that this type of reaction occurs via an ionic or radical mechanisms. The result of this reaction depends on the structure of unsaturated substrates, the phosphorus reagents, and the experimental conditions. This reaction has broad application in the preparation of an array of organophosphorus compounds.
